This invention relates generally to tractor attachments and com rises a mowe'r at- 3 tachment for -a tractor o the endless tread One of the essential obj ects of the mvention may readily attached to an, endless tread tractor and is capable of being driven from power take-off at the rear thereof.

Another object is to provide an attachment in which the ground engaging elements thereof are bodily movable relative to the tractor so that regardless of the swaying movements of the tractor such elements may remain on the ground at all times while in use..

With the above and other objects in view the invention consists of certain novel features of construction, combinations and arrangements of parts that will be hereinafter more fully described and particularly pointed out in the appended claims. s I

In the acocmpanying drawings:

Figure 1 is a perspective view of a tractor with an attachment embodying my invention applied thereto and showing a portionof the mower bar and associated elements broken away; a

Figure 2 is a s1de elevatlon of the construction illustrated in Figure 1 and showing a portion of the mower'bar' in section;

Figure 3 is a fragmentary sectional view of the rear end of the tractor and showing the connections between the pitman and the power take-'olfthereof;

Figure 4 is a fragmentary vertical sectional view through the tractor shield and showing the bracket of my attachment applied to the stationary equalizing shaft;

Figure 5 is a sectional view taken on the line 5-5 of Figure l; y

Figure 6 is an enlarged fragmentary vertl- I cal sectional view through the bracket at the attachment therefor embodyingimy 'inven- U011. As shown, the tractor is'of conventional form and hasa power take-ofi shaft '1, a tubularhousing 2 for the and a drawbar 3 at its rear end, and has a horizontal shelf 4, a vertical shield 5, a. literally proecting' stationary equalizing'shaft 6 and a longitudinally extending horizontal rail 7 at one side thereof;

The attachment B preferably comprises a w shaft 8 having a universal connection with the drawbar 3, a casting 9 of inverted channel formation roc ably mounted on'the shaft 1 at the outer end t ereof and provided at its inner end with an upwardly extending arm portion 10, a round engagin shoe 11 pivotally connected to the forwar wall 12 of the casting and provided at its rear end-with an upstanding portion 13, a mower bar 14 projecting laterally outwardly from the shoe 11, a bracket 15 rigid with the bar 14 at the inner end therofy pivoted a bolt 16 extending transversely of the portion 13 of the shoe and having'an upstanding arm 17; 18 is a ground engaging element adjustably connected to the arm 17', and '19 is a reciprocating knife on the mower bar 14. 20 is -'a counter balanced flywheel keyed upon the power take ofi shaft 1 and provided upon its outer face with an eccentric 21, and 22 is a pitman rod terminally connected to the eccentric 21 and knife 19. 23 is a bracket mounted on an extension 24 of the equalizing shaft 6 and having a laterally projecting inverted substantially channel shaped portion 5 26 and 28; 32 is a bracket i'lgid with the side rail 7 of the tractor frame; and-33 is a coil spring terminally connected to the bracket 32 and arm 26. 34 is a lever ri 'd-with the arm 10 of the casting and provi ed with a latch 35 that engages the segment 29 whereby the casting 9, shoe 11 and bar 14 may be rocked 100 ill as a unit to position the forward edge of the bar 14: and knife 19 upwardly or downwardly relative to the ground. 36 is a lever pivotally connected to the bracket 23 and connected by a series of links and levers 37, 38, 39, 40 and 41 respectively to the arm 17 of the bracket 15 rigid with the mower "bar 14 whereby the latter may be raised or lowered by the lever; 42 is a bar rigid with and projecting rearwardly from the bracket 23; and 43 is a spring terminally connected to the lever 36 and rear end of the arm 42. \44 is a rod connected to the forward wall 12 of the casting and extends through an ear 45 of the bracket 23; 46 is a nut on therod 44 at the forward end thereof in advance of the bracket45; and 47 is a coil spring 'onYthe rod 44 between the nut 46 and ear as. bracket rigid with the shelf 4, and 4Qis a rod connected to the bracket 48 and adapted to en age the mower bar 14 when it is, raised to old the same in such raised position.

Ihus from the foregoing description it will be apparent that rotation of the shaft 1 causes the eccentric 21 to reciprocate the pitman22 and knife 19. Inasmuch as the shaft 8 has a universal connection between the draw-bar 3, and the bar 28 has a pivotal connection 27 with the bracket 23, the ground engaging elements of the attachment such as the shoell', element 18, and outer shoe assembly (not shown) of the cutter bar 14 are of the full floating type and will remain on the ground regardless of the tilting or swaying of the'tractor. In this connection it will .be noted that there is a universal connection 50 between the pitman 22 and knife 19 so that the latter may beoperated when the supporting bar 14 is disposed "at various angles relative to the shoe 11. Adjustment of the .lever 3d controls the tilting position of the cutter bar 1d and knife 19 carried thereby, A

and the lever 36 may be adjusted to raise or lower the cutter bar 14 about its pivot 16.

48isa on the extension and havin a flange attachableto the lag of the shie d, a mower bar, a connection between said mower bar and brack'etgand means also connected to the w izing shaft extending through the shield, in-

cludlng an extension for the shaft, a bracket mounted on the extension andhaving a flange attachable to the lug of the shield, a mower bar, a ground engaging shoe carrying the mower bar, and connections between said bracket and ground engaging shoe and mower bar respectively.

3. A mowing machine attachment for a tractor having a laterally projecting equalizin shaft, including an extension for the sha a bracket mounted on the extension, a mower bar, a ground engaging shoe supporting the mower bar, connections between said bracket and mower bar and ground engaging shoe, and a support for the ground engaging shoe attachable to another the tractor. v

4. A mowing machine attachment for a tractor having an equalizing shaft extendinglaterally therefrom, including an extension for the shaft, a bracket mounted on the extension, a mower bar, a ground engaging shoe supporting the mower bar, a support for the ground engaging shoe attachable to another art of the tractor, a connection between the racket and ground engaging shoe operable to tilt the mower bar, and a connectlon between said bracket and mower bar operable vto raise and lower said bar.

In testimony whereof I affix my signature.

33 and 47 respectively serve as tension and compression elements for the mower assembly. v

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the sco e of what is claimed.

at I claim as my invention is:

1. A mowing machine attachment for a tractor having a drawbar at the rear end thereof, a shield at one side provided with a laterally projecting lug, and an equalizing shaft extending through the shield, includin an extension for the shaft, a bracket mounted part of
